①    If you choose to output "pressure-related data item", please contact iESLab for details.
If you choose to output "Temperature and Pressure Compensated Standard Flow", you need to define the "Standard Temperature" and "Standard Pressure".
②    If "(only) T Compensated Standard Flow" is selected, "standard temperature" needs to be defined.
③    About "Gas adaptive mechanism", please contact iESLab for details.
